Abstract

Objective: Liver transplantation is the current treatment modality for end-stage liver disease. While there is increasing drive towards early extubation in patients undergoing liver transplantation, prolonged meachanical ventilation (PMV) related to various factors can be observed. We tried to determine the risk factors associated with PMV. Methods: One hundred twenty five patients (age>18 years) of with the American Society of Anesthesiology (ASA) III-IV group undergoing liver transplantation were enrolled in this retrospective study. Patient charts, intraoperative and intensive care unit follow-up forms, and electronic medical recording system were used for data collection. Patients were categorized as having received (with) or not received (without) prolonged mechanical ventilation (>24 hours), and perioperative risk factors were attempted to determine. Results: No significant intergroup differences were found in demographic variables but ASA and model for end-stage liver disease (MELD) scores were significantly higher in the with-than in the without-PMV group. Total amount of suspension of erythrocytess suspension, fresh frosen plasm, and cell-saver blood used intraoperatively was higher in the with-PMV group but difference did not reach statistical significance. Patients with-PMV had significantly higher cryoprecipitate transfusion rates than did those without-PMV (p=0.007). While no significante intergroup differences were found in mortality and lenght of hospital stay; lenght of intensive care unit (ICU) stay was higher in the with- PMV group (p=0.001). Extravascular lung water index, global ecosystem dynamics ınvestigation, and pulse volume index values obtained from pulse contour cardiac output (PiCCO) monitorization were significantly lowver in the with- than in the without-PMV group. Conclusion: We found that preoperative high ASA and MELD scores, high blood product transfusion rates, and hypovolemia supported by the PiCCO measurements are were closely related to PMV and long lenght of ICU stay.

Özet

Amaç: Karaciğer tranplantasyonu son dönem karaciğer yetmezliği tedavisinde kullanılan güncel bir tedavi yöntemidir. Karaciğer transplantasyonu yapılan merkezlerin büyük bir bölümünde erken ekstübasyon eğilimi olmakla birlikte çeşitli faktörlere bağlı olarak uzamış mekanik ventilasyon (PMV) ihtiyacı gözlenebilmektedir.Çalışmamızda karaciğer transplantasyonu uygulanmış hastalarımızda PMV ihtiyacı ile ilişkili olabilecek risk faktörlerini belirlemeyi amaçladık. Yöntemler: Retrospektif olarak düzenlenen çalışmaya karaciğer transplantasyonu yapılan 18 yaş üstü, Amerikan Anesteziyoloji Derneği (ASA) III-IV 125 hasta dahil edildi. Hasta verileri; anestezik değerlendirme formları, intraoperatif ve yoğun bakım izlem formları ve elektronik medikal kayıt sistemi kullanılarak toplandı. Hastalar, mekanik ventilasyon ihtiyaç sürelerine göre uzamış mekanik ventilatör ihtiyacı olanlar (>24 saat) ve olmayanlar (<24 saat) olarak iki gruba ayrıldı ve PMV için risk faktörleri belirlenmeye çalışıldı. Bulgular: Demografik verileri benzer olan iki grubun ASA ve son dönem karaciğer hastalığı modeli (MELD) skorları; PMV ihtiyacı olan grupta yüksek bulundu. Kullanılan eritrosit süspansiyonu, taze donmuş plazma, cell saver kanı ve trombosit miktarı, PMV grubunda yüksek bulunmasına rağmen istatistiksel anlamlılık saptanmadı. Kullanılan kriyopresipitat miktarının, PMV grubunda istatistiksel anlamlılık oluşturacak şekilde yüksek olduğu saptandı (p=0,007). Gruplar arasında mortalite ve hastanede kalma süreleri açısından fark gözlenmezken, yoğun bakım ünitesinde (YBÜ) kalma süreleri PMV grubunda yüksek bulundu (p=0,001). Hastaların pulse contour analizi (PiCCO) ölçüm sonuçlarından elde edilen ekstravasküler akciğer suyu indeksi, global ekosistem dinamiği araştırması ve atım volüm indeksi değerleri PMV grubunda düşük bulundu. Sonuç: Preoperatif yüksek ASA ve MELD skorlarının, intraoperatif yüksek kan ve kan ürünü kullanımının ve PiCCO ölçümlerinde gözlenen hipovoleminin mekanik ventilasyon desteği süresi ile YBÜ kalış süresini uzattığını gözlemledik.
